Emerald Arborvitaes yellowing
We planted Emerald arbovitaes about 3 weeks ago in a place where our old ones, 30 yrs old, were dying. We purchased at Costco and they are on the North side of our house in East Salem, The label said to water daily 30 mins and I have but when I read online, some say only 2x a week. We planted 11 of them and it is happening badly on one and just little on the others. I am wondering if I am over watering or maybe since we back up to a Hazelnut orchard, they have been spraying a few times but I don't know what they are using. It seems the tips are yellowing and then there is healthy growth further down each branch is affects.
